2007-14 Mustang GT500 MSD 2-Step Launch Controller

When activated, the rpm will be held at a steady rpm and once the green
light comes on, release the clutch and take off - but be sure to hold
on! The rpm is adjusted with two built-in rotary dials ranging from
2,000- 11,900 rpm in 100 rpm increments. A handy LED shows when the
launch rev limit is active.
